<p>A new proposal has been announced: <a href="https://github.com/rust-lang/compiler-team/issues/332">#332</a>. It will be<br>
                announced at the next meeting to try and draw attention to it,<br>
                but usually MCPs are not discussed during triage meetings. If<br>
                you think this would benefit from discussion amongst the<br>
                team, consider proposing a design meeting.</p>

<p>I started an FCP instead of seconding it because the MCP template says public facing features need an FCP</p>

<p>Hm, afaik this would only be useable on nightly so an ordinary second would have been fine <span aria-label="thinking" class="emoji emoji-1f914" role="img" title="thinking">:thinking:</span> doesn't really matter though, does it?</p>
